If you are interested in following the Michigan Lutheran Seminary Cardinal playoffs through M-Live, you can find a preview article here. The article seems to favor Bay City-All Saints.
Unfortunately, MHSAA rules prohibit MLS from live-streaming the game. Apparently, you will still be able to find it at the MLS website and it will be posted about one hour after the game.
The following is from an MLS e-mail:
The MLS football team has made the MHSAA playoffs again this year with a record of 8-1. They will play Bay City All Saints High School on Friday, October 30, 2015 at 7:00 p.m. at MLS. Because this is a playoff game, MHSAA regulations do not allow us to livestream the game. It will be broadcast via our Cardinal Casts site one hour after the conclusion of the game. In order to access this broadcast you will need to enter the password MLS on the Cube log-in page.
Let's all cheer our Cardinals football team on to victory!
